What is important to Hanatateyama Eel Farming is
It's not "ease of growing" but "ease of growing."
Keep an eye on the eels and prepare the environment to suit their condition on that day.
We cultivate eels in cedar barrels and in the water environment, quietly bringing out their natural power.
Cedar barrel farming
At Hanatateyama eel farming, instead of using typical concrete tanks,
We use cedar barrels for farming.
This is not a choice made for appearance or tradition, but to stabilize the condition of the eel and improve its quality.
Characteristics of cedar barrels
1. Water quality is easy to stabilize
Cedar is said to be a breathable material,
It has the property of mitigating sudden changes in water temperature and quality.
Therefore, the water condition is less likely to change suddenly stress to the eels is reduced
You can create an environment like this.
2. Less stress for the eels
Cedar barrels produce less noise, vibration, and reflection than aquariums surrounded by solid walls.
This results in less unnecessary stimulation for the eels, calmer behavior, and reduced unnecessary energy consumption.
3. It works well with water circulation
The cedar barrels are designed to gently catch the flow of water and create a natural circulation. This makes it easier for the water to stagnate and reduces individual variations.
This allows us to maintain a farming environment where the fish can grow.
4. Aquaculture requires human supervision and management
Cedar barrel farming is not something that can be completed by relying solely on machinery.
The color of the water, the smell, the way the bubbles form, the movements and feeding of the eels, etc.
Daily observation and judgment determine quality.
At Hanadateyama Eel Farm, we cultivate our eels in cedar barrels, with the premise that they will be "farmed with constant human supervision."
5. Aquaculture methods that prioritize quality
If efficiency is the only goal, there are methods that are more suitable for mass production.
The reason why we still choose cedar barrels is
This is because the condition of the eels is our top priority.
By carefully assessing the condition of each eel as they are raised, we are able to produce eels with consistent meat quality.
Commitment to water
In eel farming, water is not just a facility but the environment itself.
Water quality, water temperature, water flow
At Hanatateyama Eel Farm, we view these factors as a whole and adjust them according to the season and the stage of growth.
Rather than "keeping the water constant," the water is adapted to suit the eel's condition. This is the philosophy behind the water used at Hanatateyama eel farming.
The value of stable water
How to deal with the environment
When the water is stable,
• Feed unevenness is reduced • Variation in growth is reduced • Meat quality is stable at the time of shipping
This leads to results such as:
This is directly linked to the consistent quality required for commercial use.
At Hanatateyama Eel Farm, we do not engage in unreasonable expansion or overcrowding.
• Consideration for the surrounding environment • Well-managed scale • Sustainable eel farming
We place importance on these points and cultivate our fish in harmony with the environment.
